Struct OpcDaWrapper 

pub struct OpcDaWrapper<C: ServerConnector = ComConnector> { /* private fields */ }

Concrete OpcProvider implementation for Windows OPC DA.

Heavy-weight implementation that uses the opc_da crate for native COM interop.

Implementations

impl<C: ServerConnector> OpcDaWrapper<C>

pub fn new(connector: C) -> Self

Creates a new OpcDaWrapper with the given connector.

Trait Implementations
